STUDIES ON AUTOMATIC GENERATION CONTROL OF INTERCONNECTED MULTI-AREA POWER SYSTEM

Abstract

The primary aim of AGC (automatic generation control) is to regulate active power production with respect to variable power requirements which helps in maintaining scheduled tie-line power flow and frequencies with the interconnected controlling areas at a desired nominal value. If there is a sudden change in frequency it may affect the magnetic currents in various motors(induction/transformer) and also leads to instability in various power systems. In a modern complex power system, automatic generation control (AGC) plays a major role and is becoming an essential part in order to deliver good quality of power supply to buyers irrespective of continuous power demand variations. When load fluctuation happens in a power system, AGC plays a crucial part in sustaining the optimal values of tie-line power interchange and frequency while considering step load perturbations. So, for delivering the standard power AGC system requires an intelligent and efficient controller as well as an optimization algorithm. The performance of various controllers depends upon the selection of used controller parameters as well as the specific optimization algorithm. In the literature survey, design as well as performance investigation of AGC gets more enhanced by using advanced controlling strategies and intelligent metaheuristic techniques. Therefore, a lot of research is done worldwide to provide various novel controlling strategies that are used to handle AGC problem efficiently. The main aim of the proposed work is to design a new controller and to optimize its parameters using various optimization techniques. The supremacy of this proposed approach is compared with various other controllers.
